Ridesharing companies like Lyft (LYFT) are facing a major shake-up in how they do business in California. The state senate is poised to give a final okay to a bill reclassifying drivers as employees.

PG&E (PCG) is making an offer. The electric company is planning to give $18 billion to victims, insurance companies, cities and local governments affected by the wildfires. The company’s plan filed in federal court is an effort to get out of Chapter 11 bankruptcy protection that it filed for in January.
